>>15314350Depending on your personality it could be a little grating. Her default state is being concerned for others and to make them feel welcome, but at the same time the tales of her autistic organizational skills reach far and wide so if you tend to be disorganized I'm sure that would create some friction as time goes by. Dating would be on a schedule, and after marriage I imagine so would every meal. Nobody has ever hinted at Koone being a slob.
Furthermore like all big introverts she needs alone time to recharge her ability to socialize and if she doesn't get it, she gets cranky and distant (Okayu referenced this when Korone hinted at the two living together and the reason why she never would).
Korone's also a very active dog, loves sports (baseball especially) and so despite her love for videogames, classics especially, she also has some normie habits and hobbies and lots of stamina to boot.
Also her jealousy isn't just a joke that she plays up, although it's become rather obvious when it comes to Okayu that once she knows "she's your one" and has the self-confidence that you'd never cheat her with a 他の女 she just gloats in her position as winner. But I can imagine that could be a point of contention with every woman that comes into your life for some time.
I don't know if I'd say she's the type to be irritable when stressed but it's obvious that she bottles up her concerns and doesn't know how to say "no", which is something I can very much empathize with, so you'd need to be able to tell when she's overwhelmed as she'll never let you know.
On the plus side I imagine that she'd be incredibly adorable when she wants to be clingy and cuddle. Going on dates must be hilarious and fun because of her lack of filter and saying what comes to mind. She loves horror but gets easily scared, so imagine how hard she'd cling to you during a horror movie or haunted house. And to be in her zone of affection means always being treated like the most important person in the world to her, and what man wouldn't fawn over that?
